``If this army cannot be convinced to defend its own country and religion, so as to block an invasion composed of an estimated seven to ten thousand highly-motivated volunteers making up the Sunni insurgency, there is nothing to be done. This is like Vietnam yesterday, and like Afghanistan tomorrow. If there is no real nation there -- a vigorous and alive nation, or other civilization center -- to which the majority of the population gives allegiance and loyalty -- a highly-motivated insurgent movement is unlikely to be defeated, even at these odds.''
